' SOCKET TERMINAL.

Application filed Febmgry .4, 1922. Serial no; 534,017.

. To all 'w'hom it may 60mm;

Be it known that I, LouIsE. IsELE, a citizen of the UnitedStates, residing at Glen-' ridge, in the county of Essex, State of New Jersey, have inventedan Improvement in Socket Terminals, of which the following is a specification.

Th1s invention relates to' a socket terminal and-more particularly to that type of socket terminal employed in switchjor other plugs adaptedfor use in connection with electric irons and other similar utensils in which as commonly constructed there are stud terminals to be received by the socket terminals. He'r'etofore in terminals of the type to which my invention relates,'difliculties have been experienced-iii making 'good contaots between the plug terminals of the iron or other similar apparatus and the Y sockets of the switch plug adapted to be con nected therewith. These. difliculties have arisen largely because ofthe fact that the socket. terminals as commonly constructed have not been adapted to accommodate themselves to yarious conditions, as wellas positions in. which the plug terminals may be found.

The object of my present invention is to overcome these difficulties by providing a socket terminal, the parts of which are shift- 83 As illustrated, however, one member ofableto position relatively to one another to accommodate themselves to the positions and conditions of the plug terminals, as well as to make a substantialcontactextending for practically the entire length of the plug terminal, as will be hereinafter more'particularly described. I

In the drawing Flg. 1 is a plan of one'member of. a switch plug, showing the parts associated therewith, including the socket terminals which comprise my. present invention.

Fig. 2 is a front view on an enlarged.

scale, showing the improved socket terminal.

Fig. 3 is an edge view of the'same.

Fig. 4 is a section taken on line 4-4, Fig.

2, and I Fig. 5 is an end view of the socket terminal. Referring -to the drawing, I have illustrated my invention as used-1n a switch plug,

although of course it will be understood that its use is not 'solimited as it may be employed with numerous other and similar devices.

- the switch pliig' casing is indicated at 10. Thls is provided interiorly with a recess 11,

adapted tojreceivethe base-12 of a switch mechanism. This switch mechanism-is'opem ated' by reciprocating buttons 13, and the.

base is provided with contacts '14 and 15',- by

vided with a suitable binding. post and there is also a conductor 17 extending beneath the j base 12 of the switch mechanism, and fitted with a binding post to which and the bind- .ing post associated with the-conductor 16 the lead wires are connected after having been passed through an opening provided at the endof the casing by a recess portion -18. Thecontact 15 is connected to. a ter:

minal 19 and the opposite end of-thecon-- ductor '17 is connected I to v a terminal 20, while the terminals l9 and 20 are connected to the socket terminals, forming the'present invention, these socket terminals being adapted to fit and lie within the recesses 21 and'22, provided therefor in the casing.

The casing and switch mechanism, how-,- ever, form no part of my present lnvention.

The socket terminal construction, to which present invention relates, consists in a leaf 23 which is fixed to or, integral with a head 24 having an opening 25 and oppositely dis osed flanges 26, by which the head may be tted over and connected to either of the terminals 19 or 20 by a suitable screw or otherwise. p

The leaf 23 is provided with oppositely disposed flanges 26 and 27 employed in pairs, as clearly indicated, and having inturned fingers 28 at the extremities thereof. Extending between, and lying immediately beneath the inturned fingers 28 is a sprin or resilient member '29. This, as illustrate is substantially H-shaped, so that the extremities thereof may engagewith the inner surfaces of the inturned fingers 28. In a centrally'disposed position the spring 29 is fitted with an inwardly. extending boss, 30 which may be stamped therein, as shown, or attached thereto in any desired manner. I also employ a movable or yielding leaf member 31. This is centrall ribbed as in dicated at 32 and is provide .with arecess, or openin 33 to receive the boss or projection 30 o the spring, upon which the movable or yielding member is pivotally mount- I ed and by which it is retained in position,

that is, it is prevented from shifting either laterally or lon itudinally, relatively to the fixed leaf 23, ut is permitted to swing about the boss 30 in any direction, so as to cause the yielding or.movable leaf to be turned to accommodate the plug terminal of an iron or other device irrespeotiveof the shape orcross section of the plug terminal or its direction, relatively to the plug 1 terminal with which it may be associated.

l5 5 terminal made in accordance, withithis in- It will thus be seen that evenif the plug terminals are not in alignment and whether" they are round or rectangular, the socket vention will not only accommodate itself to various conditions in use, fbutiwillalso provide a contact which extends EfOl the? portion thereof which entire length of-the plug te1'minal-,1joi* --that is inserted in' the socket terminal. I-cl'aim as my invention :f

1. A socket terminal comprisinga fixed leaf, lugs-at the sides thereof, adjacent the ends and terminating in inturned fingers, substantially parallel to the body of the fixed leaf, a resilient member maintained in position by the said lugs and fingers,

and a movable 'leafhaving a centrally 'disposed recess adapted to receive the bossof the spring member to pivotally connect the said movable leaf to the spring member.

3. A socket terminal comprising a fixedleaf having acentrally disposed longitudinal rib, lugs turned at right-angles to the body of the fixed leaf adjacent the ends thereof and terminating in fingers lying substantiallyparallel to the body of the fixed leaf,anll shaped spring secured in position by the said fingers and having a centrally fdisposedgboss "o'rrthe inner surface thereof, and a movable leaf'zflSdhaVing a centrally longitudinal ribfinwhich-there is a recess to receive 'tliebos'slon the Spring'in order to pivotally connectthe said movable leaf to the saids ring.
